In the context of database s, a single logical operation on the data is called a transaction. For example, a transfer of funds from one bank account to another, even though that might involve multiple changes such as debiting one account and crediting another , is a single transaction.

Phenolic acids phenolcarboxylic acids are a type of organic compounds. Included in that class are substances containing a phenol ic ring and an organic carboxylic acid function C6 C1 skeleton . Different categories are made of monohydroxybenzoic acid s paraben , methyl paraben , propyl paraben , dihydroxybenzoic acid s gentisic acid, protocatechuic acid , trihydroxybenzoic acid s gallic acid, phloroglucinol carboxylic acid . This type of phenolic acids especially gallic acid is a component of hydrolysable tannin s. Syringic acid , eudesmic acid or salicylic acid are other phenolic acids.
